| Performance Year | Baseline Year | |
| Total building energy consumption | 1,132,866.40 MMBtu | 866,782 MMBtu |
None
Purchased electricity and steam:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 247,451.90 MMBtu | 293,280 MMBtu |
| District steam/hot water | 0 MMBtu | 0 MMBtu |

Start and end dates of the performance year and baseline year (or 3-year periods)::
| Start Date | End Date | |
| Performance Year | July 1, 2014 | June 30, 2015 |

None
A brief description of when and why the building energy consumption baseline was adopted:
2005 is the most recent year in which we have comprehensive energy data.
None
A brief description of any building temperature standards employed by the institution:
Most OSU buildings have temperatures regulated by centralized building automation systems (BAS). The BASs adjust temperature depending on hours of occupancy for the specific building and, in some spaces, based on actual occupancy using interior sensors.
Buildings not on BAS systems also typically have some sort of timing for HVAV control.
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
LED lamps are currently being used in dozens of locations on campus, usually replacing incandescent lamps, and most recently, replacing some fluorescent as well. New construction has implemented LED lighting technology for interior and exterior application.
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Throughout campus, infrared (IR), ultrasonic (US), dual-techology (both IR and US) and photosensors are utilized to control lighting. Geosynchronous clocks are also used in many locations for outdoor lighting. Main application is common spaces such as kitchens, lounges, classrooms and lobbies, though a few buildings have sensors in office spaces as well. Newer buildings typically have building automation system-integrated lighting controls, but older buildings typically have stand-alone units.
None
A brief description of any passive solar heating employed by the institution:
None.
None
A brief description of any ground-source heat pumps employed by the institution:
A ground source heat pump is used for heating and cooling the new Oldfield Animal Teaching Facility, completed in 2012. It also has the capacity to cool a future university data center.
None
A brief description of any cogeneration technologies employed by the institution:
At the LEED Platinum Energy Center, electricity is generated in a gas turbine (fueled by natural gas), which then creates high quality waste heat. This waste heat is used to make steam for campus. The Energy Center provides about 40% of the electricity for campus.
None
A brief description of any building recommissioning or retrofit program employed by the institution:
---
None
A brief description of any energy metering and management systems employed by the institution:
All building utility data is collected and evaluated centrally. Approximately 0.4 FTE is dedicated towards managing utility data, data analysis and energy management.
Additionally, many of our buildings are connected to building automation systems (BAS) that centrally manage building energy consumption.
FY15 saw the implementation of advanced metering program with interval data available on public dashboards for 20 core campus buildings.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
OSU Construction Standards conform with Oregon Specialty Energy Codes that require high efficiency equipment and standards for buildings.
None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
Trees are used in some landscape applications to provide shade to west and south sides of buildings.
None
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
All machines are required to have miser control technology since the last renewal of the contract.
None
A brief description of other energy conservation and efficiency initiatives employed by the institution:
